Raised by Wolves. Sky. Second series of the enigmatic and dark SciFi production that looks yet again at the relationship we might have with sentient machines we may create in the future. Sounds far fetched ? ... but I worked on Neural Networks some years back. They are based on the way the human brain works, although at that time far far less complex. But looking at how electronics and software has progressed in the last 30 years, and will probably progress further at an ever accelerating rate, a sentient machine is not so scifi comic anymore, and it might not so be a renegade robot, or a computer with a metallic voice, but something we can't begin to understand.
